:MARKers Subsystem
The Markers (MARKers) subsystem commands control up to 16 markers.
For all markers:
- Use the
:MARKers:SHOWcommand to display any hidden markers. - Use the
:MARKers:MINTensitycommand to adjust the brightness of all marker information on the display. - Use the
:MARKers:HIDEcommand to hide all markers without changing any of the marker settings. - Use the
:MARKers:OFFcommand to turn all markers off and "default" their settings.
For individual markers:
- Use the
:MARKers:MARKer{N}:STATecommand to specify whether a marker is shown, hidden, or off. - Use the
:MARKers:MARKer{N}:SOURcecommand to associate a marker with a source waveform and its window and grid. - Use the
:MARKers:MARKer{N}:TYPEcommand to specify the marker type. - Use the
:MARKers:MARKer{N}:MNAMecommand to change the marker name. - Use the
:MARKers:MARKer{N}:CENTercommand to change the grid's horizontal position in order to center the marker. - Use the
:MARKers:MARKer{N}:DELetecommand to turn off a marker and reset the marker settings to its defaults.
Tracking Marker Positions
When positioning a tracking marker between waveform sampling points, the marker's time position and associated y-axis value may be restricted. Because there is normally an abundance of waveform sampling points on screen, you may seldom notice that a marker is restricted to specific positions and values.
| Marker X-Axis Position | Marker Y-Axis Value |
|---|---|
| Non-Spectral Waveforms: | |
| restricted to sampling- point position |
nearest sampling- point value |
| Spectral Waveforms (such as created by the FFT function): | |
| always restricted to sampling-point position | always nearest sampling-point value |
